Re: How to fix Intel H2O 16MB BIOS on Lenovo Ideapad 3 15IML05 NM-C781
Go to the lenovo support site,enter the serial number to find the bios update .Open your backup with a hex editor, search for the word BVDT,you`ll see the bios version DXCN34WW, the latest version from support is DXCN39WW,donload it, extract the first exe using innoextract and the second exe using 7-zip or winrar.Open BIOS.fd ,search for img or biosimg. The off-sets are 12EA10 - 112EA0F (length 1000000) copy into a new file and save.
The DMI in your backup is encrypted, search for the word LENV ,there`s 2 LENV areas to copy ,the off-sets are 522000 - 523FFF (length 2000), copy it into the virgin bios using the same off-sets, thats it .
